The principal object of the invention is to provide a pipe which willeliminate contami nation of the natural aroma of the tobacco throughnoxious secretions and which will 5 remain sweet and clean.

A further object is to devise a construction of pipe which will besimple and inexpensive to manufacture and which. will be devoid ofpockets to harbor noxious'elements.

a The principal feature of the invention consists in the novelarrangement of a tubular resilient member surrounding and embracing ametal stem which extends from the pipe bowl to the mouth piece andforming a seal to prevent the seepage of moisture around the metal stem.

In the accompanying drawings, Figure 1 is a longitudinal mid-sectionalview of a pipe constructed in accordance with this invenc tion.

Figure 2 is a longitudinal sectional view of a slightly modifiedconstruction.

Figure 3 is a perspective detail of the resilient sealing member.

I]. Figure 4 is a perspective View of the plug for retaining the sealingmember in the pipe stem.

In the manufacture of tobacco pipes it has become almost universal toincorporate a metal tube into the stem to prevent the moistureaccumulating in the smoke passage from perm-eating the wood of the bowlstem and also to facilitate the cleaning of the smoke passage ofaccumulated moisture, tobacco 5 particles and ash.

It is found however that the moisture seeps around the metal tube andits exterior becomes coated as also does the wall of the passage throughwhich the metal tube extends.

' The present invention effectively overcomes this latter objectionablecondition. In

the construction illustrated in Figure 1 the stem 1 of the pipe 2 ispreferably bored with a cylindrical orifice 3 from the outer end to 5 apoint close to the bowl and a small hole 4 extends from the axis of theorifice 3 into the interior of the bowl.

A tubular length of resilient material 5 such as cork, or rubber, isinserted into the orifice 3 to abut the inner end thereof and 7 tube.

. The tubular member 5 is securely held in place by a cylindrical block9, preferably of wood which is pressed into the orifice 3 after theinsertion of the member 5 and this block is preferably cemented in placeand holds the member 5 under a slight longitudinal compression.

- The hole 10 in the block 9 is a free fit'fo-r the metal tube 7 and atits outer end is slightlychamfered to guide the metal tube thereinto.The use of the wood block also prevents the metal tube from cutting theresilient member 5.

The reduced end 11 of the mouth piece 8 fits into the bore 3 in theusual manner.

It will bereadily appreciated that in providing the tubular member 5 ofa resilient material and securing it in the pipe stem under slightcompression it will retain indefinitely a snug fit around the metal stemand will effectively prevent moisture from seeping around the outside ofthe metal tube and it will also prevent moisture from. accumulating andsaturating the bowl as there are no interstices or pockets to harbor themoisture.

lVhen cork or other soft substance is used in the construction of themember 5 it is preferably coated with a non-absorbent yet elasticsubstance such aspyroxylin or paraffin wax. These substances will notdetract from its resilient contact with the metal tube and they willeffectively prevent" absorption though there is very little possibilityof the member 5 actually contacting with themoisture as it effectivelyseals the outer surface of the metal tube.

It may, in some designs of pipes, be found desirable to secure the metaltube in the bowl stem, as illustrated in Figure 2 and arrange theresilient sealing member in the mouth piece. In such an arrangement themouth piece is bored with a hole 12, similar to the bore 3 of the pipestem and the tubular 1nem ber 5 is inserted therein and secured by aplug 13 which may be either threaded as shown, or cemented in the outerend, the plug being left protruding to form the reduced end 1 1 of thestem to be inserted into the bore of the pipe stem.

Pipes constructed as described are of extremely simple construction andmay be manufactured at very little cost over the ordinary type of pipe.

The invention is shown as applied to tobacco pipes but it maybe readilyapplied .to cigar and cigarette holders.

. lVhat I claim as my-invention is:

1. A tobacco pipe having an orifice in the stem, a resilient tubularmember secured in the inward end of said orifice, means insertedintosaid orifice-securing-said resilient member therein, and a removablemetal tube extending into said tubular resilient member and engaging insealing contact therewith.

2. A tobacco pipe having a cylindrical orifice in the stem, a tubularlength of resilient material enclosed within said orifice at the inwardend adjacent to the bowl, a block closing said orifice and abutting saidlength of resilient material and having a hole therethrough-in alignmentwith the central opening of the tube, and a removable metal tubeinsertedthrough said. resilient tube'and retaining a pressure contacttherewith.

8. A tobacco pipe having a cylindrical orifice in the stem and arsmallerorifice leading into the bowl, a'tubula-r length ofresilient materialfitted into said cylindrical orifice and abutting the inner end thereof,a block secured in said cylindrical orifice and abutting the outerend ofsaid resilient tube in pressure contact,-said block having a centralorifice slightly-larger than'the orifice in the tube, a mouthpiece'fittingin'the open end of said cylindrical orifice, and 'a metaltube secured in said mouthpiece and extending through said block andresilient tube and engaging the inner wall of the tube in pressurecontact.

4. A tobacco pipe having a cylindrical bore in the stem extending closeto the-bowl and anaxially arranged hole of smaller diameter than saidbore extending into the bowl, a tubular length of" resilient materialabuting the inner end of said bore, a hard cylindrical block cementedinto the bore and abutting the resilient-tube in pressure contact andhaving a central orifice slightly larger than the inner diameter of saidtube, a mouth piece having-a reduced end fitting the stem bore, and ametal tube secured in'thefmouth piece and extending through said'blockand said resilient tube, the outer diameter of said metal tube being ofslightly larger diameter than the bore of the resilient tube and en'-gaging; said tube in a compression seal.

5. A tobacco pipe having a stem formed with a cylindrical bore, a metaltube extending axially through said bore, and a tubular length ofresilient material secured in said bore and surrounding and embracingsaid metal tube in sealing contact, said resilient tube having aresilient fluid resisting coating.

6. A tobacco pipe having a stem formed with a cylindrical bore, and ametal. tube ex tending axially through said bore, and a tubularlength-o'f cork secured in said bore and embracing said metal tube in afluid seal, said cork having a pyroxylin coating rendering it liquidproof.

7. A tobacco pipe having an orifice in the stem, a "resilient tubularmember secured in the inward end-of said orifice and abutting theshoulder formed at the inward end thereof in sealing contact, a mouthpiece, and a tubular extension from said mouth piece extending into.said resilient tubular member and engaging the inner wall .thereof insealing contact.
